In my FrameMaker template I was missing a font called "Palatino". I changed the font in the template to another font that is available with me.

I changed the font in every Paragraph tag and Character tag in the template. And did Global Update. I double checked everything.

I did it manually in one of the files and imported to the other files.

But in some of the book files, I am still getting the missing font alert for "Palatino". It is a mystry for me, where I am leaving some track of the old font. I am 100% sure the font do not appear in any of the Paragraph tags and Character tags in the template

Or you can deactivate "Remember missing font names" in the Preferences and then open your file. FrameMaker will permanently replace Palatino with another font. Only if the font is used by a graphics file, FrameMaker will still try to find this font.
